syslog extract of nouveau DRM exception while watching a movie with mplayer

Similar behave here.
Here it is my environment:
Software
OpenSUSE 12.1
/lib/modules/3.1.9-1.4-desktop/kernel/drivers/gpu/drm/nouveau/nouveau.ko
xorg-x11-driver-video-nouveau-0.0.16_20110720_b806e3f-2.1.2.x86_64
xorg-x11-7.6-67.3.1.x86_64

Hardware:
02:00.0 VGA compatible controller: nVidia Corporation C77 [GeForce 8300] (rev a2)
Motherboard: ASUS Product Name: M4N78 PRO
CPU: Phenom II Family 16, Model 4, Stepping 2 3400 MHz

While watching movie with mplayer randomly nouveau seem to crash freezing the X11 session.
It's possible to connect to the system using ssh but it isn't possible to kill xorg processes. 
Here are the last entries of the Xorg.0.log:
